Abstract
Настоящее раскрытие описывает различные антенные блоки, в каждом из которых антенная катушка размещена вокруг корпуса прибора в антенном тракте. Антенный тракт проходит через чередующиеся канавки и площадки. В каждом из вариантов по меньшей мере одна из канавок расположена в корпусе в неосевом направлении относительно продольной оси корпуса. Антенная катушка может представлять собой осевую катушку или наклонную катушку. Могут быть включены дополнительные канавки, ориентированные в осевом направлении. Также описаны способы, включая способ сбора множества пар данных, каждая из которых содержит индуцированный сигнал в приемнике и соответствующий угол торца прибора, с помощью прибора, содержащего по меньшей мере один раскрытый в настоящем описании антенный блок, и способ генерации результатов измерения, содержащих информацию о направленности формации, путем вычисления площадей областей, задаваемых функцией индуцированного сигнала, аппроксимированной множеством пар данных.
